Topic: Effects of Metformin on Advanced Glycation End Product Formation in Bone under Hyperglycemic Conditions

Abstract:
Diabetic patients have a higher rate of bone fracture and bone fragility compared to nondiabetic patients. A characteristic of Type 2 Diabetes Mellitus (T2D) is elevated blood sugar concentrations which means the tissues of the body are in hyperglycemic conditions. High blood sugar has been shown to increase nonenzymatic crosslinks between collagen fibers, known as Advance Glycation End-products (AGEs), in bone tissue and reduce the quality of the bone. Metformin is a commonly prescribed drug for T2D patients to reduce blood sugar spikes but has also been shown to reduce AGEs in other tissues in previous studies. In order to find a way to reduce AGEs in bone, and therefore increase bone quality, our hypothesis is AGE formation will be reduced when bone tissue is incubated in hyperglycemic conditions with metformin.

TOPIC:
Using computational simulations to develop a fundamental understanding of the governing fluid dynamics of surfactant replacement therapy in treating preterm infants with respiratory distress syndrome
ABSTRACT:
The aim of this research is to improve the effectiveness of surfactant replacement therapy (SRT) in treating preterm infants with respiratory distress syndrome (RDS) through computational simulations. RDS is caused by a pulmonary surfactant deficiency within the lung, a surface-active molecule necessary for normal breathing operation. Infants born prior to this stage of development (37 weeks) are susceptible to breathing difficulties, and atelectasis, which unfortunately, is the leading cause of mortality in preterm infants. The most common treatment procedure SRT, seeks to replace the missing surfactant in the infant's lung, with the ultimate goal of achieving uniform film distribution and reaching the alveoli at the terminating branches of the airway. Although, relatively effective, SRT has a 35% non-response rate. The low response rate is attributed to the complexity of the human lung, spanning 15 continuously-branching airway tubes which successively become narrower, shorter and more numerous. With the delivery mechanism of surfactant relying on the fluid dynamics in each airway, the consistently changing geometry of the lung makes it extremely difficult for medical practitioners to effectively deliver surfactant plugs uniformly through the airway tree. We seek to better understand the fluid dynamics of surfactant plug transport which contribute to the non-uniform film distribution in the lung. The key principles include: the effect of gravity on plug transport in straight tubes and the relationship between Capillary number and gravity on plug splitting in bifurcating airway models of two- and three-generations. Furthermore, a novel method of surfactant delivery is proposed to overcome the effects which lead to asymmetric film distribution in the airway. The method, muilti-plug aliquot delivery shows improvement in the overall homogeneity of surfactant delivered into the lung, when compared to the traditional method of single dose instillations

Meeting ID: 964 8496 9858
Passcode: 007589
Abstract:
Given the documented challenges among students with college mathematics, this narrative inquiry investigates five students' lived experiences with mathematic learning. Unlike existing studies that concentrate on student deficits in terms of their learning and performance, this study is aimed to probe students experiences related to mathematics learning with a focus on the notion of mathematical identity from an anti-deficit perspective. Grounded on sociocultural theory and identity as an analytical tool, the goal of this research is to understand complexities inherent in mathematics learning shaped by learning context and students' developed sense of self as mathematics learner. Drawing from narrative interview study and listening guide methodology, the study findings reveal the complexity and fluidity of every participant's mathematical identity and suggest important commonalities among them, with regard to how their identities impacted by factors both inside of mathematics classrooms (tests scores, experience with teachers and friends) and outside (such as master narratives about mathematics in the society).

- Description: Topic: Reliability Analysis of Storage Area Networks with Cascading Failures
ZOOM Teleconference: https://umassd.zoom.us/j/98720525649
Abstract:
During the coronavirus pandemic, telecommuting is widely required, making remote data access grow significantly. This requires highly reliable data storage solutions. Storage area networks (SANs) are one of such solutions. To guarantee that SANs can deliver the desired quality of service, reliability modeling and analysis are crucial. A challenge to analyze the reliability of SANs is to address cascading failures that occur when a single initial incident (e.g., the malfunction of one device, overload, extreme weather) triggers a cascade of unexpected failures of other devices. The existing works of considering cascading failures have been mostly centered around traditional power systems and smart grids. In this work, we model the effects of cascading failures triggered by the data overload of devices in SANs. The proportional hazards model and accelerated failure time model are used to describe the relationship between the load and failure behavior of an SAN device. A detailed case study of a mesh SAN system is performed to illustrate the proposed method for the SAN reliability analysis considering cascading failures.
Note: All ECE Graduate Students are ENCOURAGED to join the zoom teleconference. All interested parties are invited to join.

Abstract
In coastal communities water quality effects all aspects of life. With predominantly residential development, the major pollutant of concern is nitrogen (N) generating a need for N remediation tools. My thesis focuses on three non-traditional N reduction approaches that stimulate denitrification, and identification of best practices to ensure N reduction goals are met.
In Chapter 1, I propose to assess the potential for denitrification associated with oysters, through measurement of shell, tissue, and whole live oysters, and to assess the rate and amount of denitrification from individual incubations. This effort completes a larger effort to determine the mechanisms by which oyster aquaculture can be employed as a N removal method. At present coastal communities have begun to implement aquaculture to reduce estuarine N levels.
In Chapter 2, I propose to determine if removable permeable reactive barriers will stimulate denitrification in active cranberry bogs. Deployment of permeable reactive barriers within this type of system is yet unproven, but could significantly increase N removal beyond what naturally occurs. Monitoring of the field deployments and evaluation of the nutrients both up-stream and down-stream of barriers will be used to determine the rate of N removal.
In Chapter 3, I propose to determine if aquatic plants in freshwater ponds remove more N through uptake or denitrification in associated epiphytic communities, and if they can be harvested as a N management tool. Evaluation of N uptake by plants and measurement of denitrification rates of the epiphytic community in comparison to other nutrient sources and sinks in the ecosystem will be used to determine the relative importance of each process.
The proposed work will address unknowns regarding sites and rates of denitrification in coastal systems that can be used as non-traditional cost-effective nitrogen reduction techniques that can be deployed in coastal watersheds to meet communities’ Clean Water Act requirements.
